Oil boiler and storage tank servicing & installation.
Oil Boiler Installation
If your property runs on oil, it’s essential that any installation or servicing work is carried out by a properly qualified engineer. We are fully OFTEC-registered, which means we’re approved to safely install, service and maintain oil-fired boilers to the correct industry standards.
Oil heating systems are commonly found in rural and off-grid homes, and they require specialist knowledge to keep them running efficiently and safely. Whether you’re installing a new oil boiler, booking an annual service, or dealing with a fault, you can be confident all work is completed correctly, certified where required, and in line with current regulations.
We provide a professional, straightforward oil boiler service for homeowners who want reliability, clear advice and workmanship they can trust.
Oil Boiler Servicing & Maintenance
Regular servicing is essential to keep an oil boiler running safely, efficiently and reliably — particularly in rural and off-grid homes where heating problems can’t be fixed quickly by switching suppliers or networks.
As OFTEC-registered engineers, we service oil-fired boilers in line with manufacturer guidelines and current safety standards. A proper service helps reduce the risk of breakdowns, improves efficiency, and can extend the lifespan of your boiler while keeping warranties valid.
During a service, we carry out a full safety and performance check, clean key components, inspect the burner and fuel supply, and identify early signs of wear or faults before they turn into costly repairs. We’ll also give you clear, honest feedback on the condition of your system — no scare tactics, no unnecessary work.
We recommend annual servicing for most oil boilers, ideally before the colder months, to ensure dependable heating when you need it most.
Why Oftec Accreditation is Important
We are fully OFTEC-registered, which means we’re qualified and approved to install, service and maintain oil-fired boilers safely and correctly. OFTEC accreditation confirms that our work meets current industry standards and Building Regulations, giving you peace of mind that your heating system is in safe hands.
Using an OFTEC-registered engineer also ensures any required certification is issued correctly, helps protect manufacturer warranties, and confirms that work has been completed to recognised safety and quality standards.

How long do oil boilers last?
With proper installation and regular servicing, an oil boiler will usually last between 15 and 20 years. Poor maintenance can significantly shorten this lifespan.
Servicing helps identify small issues early, preventing premature failure and expensive repairs.
Are oil boilers environmentally friendly?
Traditional oil boilers are less environmentally friendly than some newer heating technologies, but modern oil boilers are far more efficient than older models.
Newer systems burn fuel more cleanly and use less oil to produce the same heat. There are also developments such as biofuel blends that aim to reduce carbon impact over time. For many rural properties, a modern, well-maintained oil boiler can still be a sensible balance between performance, cost and environmental impact.
How often does an oil boiler need servicing?
Most oil boilers should be serviced once a year. Annual servicing helps keep the system running efficiently, reduces the risk of breakdowns, and ensures it remains safe to use.
It’s particularly important for oil boilers because they have more moving parts and combustion components than gas systems, which can wear or clog over time.
Is servicing legally required?
There’s no legal requirement for homeowners to service an oil boiler every year, but it is strongly recommended. Regular servicing helps meet safety obligations, keeps the system compliant with manufacturer guidance, and is often required to maintain warranty cover.
Any work on an oil boiler should be carried out by a OFTEC-registered engineer such as Holt Plumbing and Heating
